Good point about tuning a ground wire! Ten Tec makes a ground tuner in a fine little kit. Using their toroid from their L net tuner of many years. For $49, it was a great buy a few years back. I reco

While this works, be advised that the end of each 1/4 wave presents a very high voltage which can be in the order of a couple of thousand volts. If one is using a center fed balanced antenna system,
I am not sure about the effectiveness of aluminium in shielding "magnetic" fields. It seems that a high mu metal is the way to go for magnetic shielding. That is what they used on CRTs to prevent ma

Yes, I think both Tentec and another company makes a "ground" tuning network. It works, but means that one has a portion of their ground system that radiates. 73 Bob, K4TAX __________________________
At 60 Hz or audio frequencies aluminium is not effective in shielding against magnetic fields. However, at radio frequencies it works very well, provided that the circuit to be protected is completel

Thanks for the info. I guess the shielding using ferrous (hi mu) was for low frequencies. 73, Jim wd4air _______________________________________________ TenTec mailing list TenTec@contesting.com http
